A paper filter at the bottom, another filter (= barrier) at the top, a blooming phase, then 2 bar - sounds like an Aeropress to me

There is an espresso basket in there too and the decent is controlling the flow a little more consistently i suspect . The grind i think will be alot finer than anyone uses in a aeropress . 

I do a blooming shot ( not decent , bianca ) 

2 bar pre , 20 seconds bloom then 6-7 bar after , currently no paper involved . 


I write a blog, it's nothing to do with coffee ...

60lb of plunge pressure?

The AeroPress filter is 2.5 inches in diameter so the area of the filter is 4.9 square inches. If you press down firmly on a scale, it is relatively easy to get the scale up to 25 pounds and then if you press hard on the scale, you can certainly get it up to 50 pounds. Therefore if you press similarly hard on your AeroPress while brewing coffee, the firm pressing will be at 5.1 psi (25 lbs/4.9 sq in) and the harder pressing will be at 10.2 psi (50 lbs/4.9 sq in). Since a bar of pressure is 14.7 psi, the former is .35 bar and the latter is .70 bar. We have done taste comparisons between minimal and maximum pressure on an AeroPress and our taste buds can’t tell the difference.

If you get 2 bar with the Aeropress, you must be jumping on it.

Smart Espresso Profiler (SEP) & Decent

I was in Berlin last week at the world of coffee tradeshow, where I finally got to meet Gabor,  the genius behind  my favorite coffee related films https://vimeo.com/306859922, who also happens to be (along with Miklos)  behind the smart espresso profiler https://www.naked-portafilter.com/smart-espresso-profiler/

I pulled a wonderfully sweet and interesting lever shot using SEP, though I decided not to follow the existing trace, and instead tried to use a declining pressure profile by hand to maintain stable flow. Their software has a nice feature where your shot along with a photograph gets emailed to you, so let me duly comply with their social media strategy and post it here.

I can also report back at the SEP software can now export traces, which can then be imported into "God Shot" traces on the decent espresso machine.   You can import them into the android version of the decent espresso software, as well as the Windows, Macintosh or Linux version.

To import an SEP shot, copy the CSV into this directory where your decent espresso software runs:
/de1plus/godshots/import/common

The next time you run the decent espresso app, the traces will be imported. You can find them by tapping the "heart" icon in the decent espresso app. In this case this was espresso #181:

And when imported it caused a trace to appear in the  decent espresso app.

I just tested it, and it worked fairly well.

If you look at the debug log when my app runs, this is the information that appears, which gives quite a bit of detail. It looks like I have a small error parsing the date.

Also, I apparently am converting the flow information into volumetric flow (blue line) in my software, where’s it should be charted as gravimetric flow (brown line).

However, these are very small things, that I can fix tomorrow. It basically works already, quite nicely.

A very brief view of Decent Espresso at the World of Coffee show.  

Very, very busy for 3 days, as Scott Rao was pulling his 28% extraction shots. Lots of coffee celebrities (and the "little people" too) came by to taste.

Decent ♥️ Niche 

I'm today a proud owner of a Niche Grinder https://nichecoffee.co.uk which I'll be using when I'm "on the road" and away from home.  I love my Lynn Weber EG-1, but at 30kg, it's a lot to lug around, and the Niche does a very capable job of producing tasty espresso with the Decent about 1/5th the carrying weight. At 1/5th the price of the EG-1, it's nonetheless a very competent grinder, and my recommendation for all home purchasers of the Decent espresso machines.

A recent survey of Decent owners found the Niche to be the most popular grinder among them, with 17% of Decent owners, also having a Niche.

Two weeks ago, Bugs and I visited Martin (inventor/founder/owner) of Niche, and greatly enjoyed two British pub meals, and a detailed audit of the Decent internals by super-experienced home-appliance engineer Martin.  

I love the clarity of Martin's vision for the Niche, and how cleanly and successfully he's executed on that.

The base is a wide square sheet of solid metal, about 1cm thick, painted back, so that it can suspend the grinder in mid air.  Like a square tripod, but with sand-bags built in.

Beautiful and works well once on the counter top, but really heavy to lift.

Note that 29.5kg was the packed-in-a-case weight, and I'm sure the suitcase added some weight.

That makes sense. Beautiful looking grinder though. And as ever with LW, well engineered I'm sure. Have never had the joy of trying one

The upcoming "group head controller" 

Starting in November, the Decent Espresso machines will have this circular, glass-covered controller on the group head, sitting on top of a circle of full color LEDs.  

You'll be able to start/stop all functions (espresso, steam, etc) and you'll also have real-time "tap and drag" finger control over either pressure or flow (whichever you tap closest to).  The tablet's charts follow you, showing what you're requesting (the dotted lines) and showing you what's actually occuring to your shot.

Green (pressure) and blue (flow) leds on the white ring will give you real-time readings of pressure and flow.

The price for our machines will go up by $300 for this feature, starting in November.  And.... customers who have our v1.1 espresso machines (that's what we're currently making, since January 2019) will be able to install this upgrade on this machines, for the same price ($300).

Attached is a photo of our "manufacturing prototype".  We're still nailing down the final issues, such as how to align the icons perfectly, guarantee water tightness, testing insulation and heating over heavy use.

This new controller is key to a few new things:

  1. real time control over flow and pressure
  2. UL approval (we'll be submitting this model for approval, and we think it'll pass).
  3. heavy duty use (ie a café), that a tablet could probably not withstand
  4. the tablet becomes optional, for cases (especially cafes) where a tablet might not be wanted

I like the look of that. Gives an easier span of control if you want it. Nice that it's upgradeable too.

"A business run out of a suitcase"

Here is a more detailed photograph showing the white DE1XL and pitcher rinser, built into a suitcase.

I was waiting for someone to tell the joke about how we were a "business run out of a suitcase" (that's an English-language expression meaning "they are such a small business, that they have no office")

I'll be making a short video soon, about the suicase, how it went, and also showing the wiring from behind.

One unexpected benefit was how the suitcase lifted the machine up to a better height.

A Coffee Cart, in a Suitcase

For our trade show stand, we modified one of our Decent suitcases to hold a pitcher rinser and espresso machine, with all the plumbing built in.  Makes for a clean setup with a very fest setup and tear down.

How do you move the niche grinder? In it's original box or is there a suitcase for that too?

I believe that by reorganising the foam & putting a couple of items in the Machine they can get the Niche into the suitcase. Great - ingenious.

I've been watching this since day dot, and was just looking around on the Decent website - still contemplating a possible purchase - and I noticed that one of the previously interesting and useful design features (the angled lower front panel section) is effectively removed from the DE1+ because of the brushed finish all over the front, including the angled mirror section.    If I want a mirrored section  to easily gaze at my extraction, then it appears that my only option is to go for a PRO or higher model - or I now have to comtemplate the addition of an adhesive mirror strip... seems odd that the angled section isn't a polished mirror finish on the DE1+.

To help me in my decision making - will ALL features of the forthcoming 1.3 be available as upgrade parts to the current model, at the price delta - or is the touchcontrol group cover the only one?  (so will current model + $300 upgrade = v1.3 spec, or will there be other differences).

At the moment, I'm carrying it in its original suitcase.

However, if I put the ceramic water tank and drip tray under the machine when I pack it, there's enough space for the Niche in the same suitcase. 

However, I'm unsure if the ceramic will break in that configuration, and I don't have a spare ceramics set with me here in the UK, so I haven't experimented yet.  But I'll be giving that a try shortly, as a "one suitcase" espresso setup is a bit too seductive an idea not to try to make it work.

For $99, granted.   or £2 for a thin (1mm thick) piece of mirrored acrylic and a few blobs of superglue.

Yes, all parts for all our models can be purchased separately.

However, it's a good 2 hours of work to replace the mirror panel by hand.  There's a video in our docs on how to do it, but it's a lengthy job, and you need to be unintimidated by taking apart a machine.

It's made from pre-mirrored stainless steel which we import from Korea. It's 2mm thick, and we get about a 40% quality-control failure rate on it, as they tend to get scratched up before we even receive them.  It's one of the most frustrating parts for us to make. I posted extensively about it last year, as we were (at the time) paying USD$40 each (at quantity) to have them CNCed for us by a specialist.  We tried 3 different Chinese suppliers of mirrored stainless, and found them all to be scratched. The Korean stuff is way more expensive, but much less likely to suffer scratches.

The 40% that are quality-control failed (minor scratches when we peel off the protetive film), we then send to another company in HK, who brush-steel treats the front face, thus removing the mirror finish, and therefore getting it into a state that we can use it.  That way we don't waste any.

So that's why it's an expensive part, and also why the brushed steel appears on the lower-priced DE1+ model.  Really nicely mirrored stainless, that's bent and cut, is hard to do.

I am also thinking about DE1 and which model to go for. I prefer to get a cheaper version provided that it could be upgraded when needed (a kind of a Gaggia Classic route when you can add PID, etc later).

It is a great idea to add a mirror strip to DE1+. Another option which I do not like on DE1+ is the mesh shower screen. I have both for my Gaggia (IMS mesh and "competition"), and seems the competition "taste" better. This is probably because it restricts the water flow less, given that the vibration pump does not provide good flow in the first place.
